Name of the Patient : Abc Xyza M. Glmn / F / 45 yrs.
Referred by : Dr. Abc Xyzrekh.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to BLE with paresthesias since 1 year.

EXAMINATION :

M.R.I of the lumbo-sacral spine was performed using the following parameters :

5 mm thick T1 Weighted and T2 Weighted sagittal images.

5 mm thick T1 Weighted and T2 Weighted axial images.

OBSERVATION :

There is loss of normal lumbar lordosis and loss of water content of the L2-L3, L3-L4 and L4-L5 intervertebral discs.

There is a fairly large, posteriorly extruded disc at the L4-L5 level with thecal sac compression and bilateral neural foraminal narrowing. There is indentation on the traversing L5 nerve roots bilaterally. There is also slight facetal hypertrophy and canal stenosis at that level.

Minimal, posterior disc bulges are noted at the L3-L4 and L5-S1 levels.

Anterior disc herniations with anterior peridiscal osteophytes are noted in the lumbar region.

Type II degenerative marrow changes are noted adjacent to the L2-L3, L3-L4 and L4-L5 intervertebral discs.




Schmorls nodes are seen at the L3 and L4 vertebral levels.

The pedicles of the lower lumbar vertebrae appear smaller in their antero-posterior dimensions.

The rest of the lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The rest of the facet joints and the visualized pre and paravertebral soft tissues are unremarkable.

The conus medullaris terminates at the L1 level and the thecal sac terminates at the S1 level.

Fat is noted in the filum terminale over the L3 to S1 vertebral levels.

The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :

16.0 mm at L1-L2
14.0 mm at L2-L3
12.0 mm at L3-L4
7.0 mm at L4-L5
8.0 mm at L5-S1.

IMPRESSION :

1. A fairly large, posteriorly extruded disc at the L4-L5 level with indentation on the traversing L5 nerve roots bilaterally with facetal hypertrophy and canal stenosis at this level.

2. Congenitally short pedicles of the lower lumbar vertebrae in their antero-posterior dimensions.
